Automobile data transmission

1. A method comprising:

a) recording and time stamping automobile data obtained from a plurality of sensors installed in an automobile;

b) transmitting, by a wireless device, a random access preamble on a first plurality of orthogonal frequency division multiplexing (OFDM) subcarriers of an uplink carrier to a base station when a pre-defined condition is met based on at least one of the following:

i) said automobile data;

ii) the current time; and

iii) a user input;

c) transmitting a first message destined for a server in a communication network, by said wireless device to said base station over a non-guaranteed bit rate (non-GBR) bearer, said first message encrypted using a first encryption key; said first message configured to trigger establishment of a connection to said server;

d) receiving, by said wireless device, a second message originating from said server from said base station over said non-GBR bearer, said second message configured to cause the start of transmission of said automobile data from said wireless device to said server; said second message encrypted using a second encryption key;

e) encrypting, by said wireless device, said automobile data using said first encryption key; and

f) transmitting, by said wireless device, said encrypted automobile data to said base station, said base station configured to decrypt said automobile data before forwarding said automobile data to said server.

2. The method of claim 1 , further comprising receiving, by said wireless device, at least a part of said automobile data via a short range wireless technology.

3. The method of claim 1 , further comprising pre-configuring in said wireless device:

a) said network address of said server; and

b) said network address of said wireless device.

4. The method of claim 1 , further comprising receiving a control message on a first data channel on a downlink carrier before establishing said non-GBR bearer, said control message establishing a first signaling bearer, said first signaling bearer established on said downlink carrier and said uplink carrier.

5. The method of claim 1 , wherein transmitting said encrypted automobile data comprises transmitting a plurality of data packets.

6. The method of claim 5 , wherein transmitting said plurality of data packets comprises transmitting each of said plurality of data packets in two parts, a first part is transmitted on a fourth plurality of subcarriers in a first time period, and a second part is transmitted on a fifth plurality of subcarriers in a second time period, wherein:

a) said first time period and said second time period do not overlap;

b) said fourth plurality of subcarriers and fifth plurality of subcarriers are different;

c) said fourth plurality of subcarriers consists of a plurality of contiguous subcarriers; and

d) said fifth plurality of subcarriers consists of a plurality of contiguous subcarriers.

7. A method comprising:

a) recording automobile data obtained from a plurality of sensors installed in an automobile;

b) transmitting, by a wireless device, a random access preamble on a first plurality of subcarriers of an uplink carrier to a base station, when a pre-defined condition is met based, at least in part, on said automobile data collected from said plurality of sensors or the current time or a user input; the transmission timing of said random access preamble determined based, at least in part, on a synchronization signal received from said base station;

c) receiving, by said wireless device, a time alignment command from said base station in response to transmitting said random access preamble;

d) adjusting uplink signal transmission timing of said uplink carrier according to said time alignment command causing substantial alignment of frame and subframe reception timing at said base station of said uplink carrier;

e) generating encrypted automobile data by encrypting said automobile data using a first encryption key; and

f) transmitting, by said wireless device, said encrypted automobile data to said base station employing an established non-guaranteed bit rate (non-GBR) bearer, said base station configured to decrypt said automobile data before forwarding said automobile data to a server in a communication network.

8. The method of claim 7 , further comprising receiving an Internet protocol address from said base station over a second plurality of orthogonal frequency division multiplexing (OFDM) subcarriers of a downlink carrier before transmitting said automobile data; said downlink carrier corresponding to said uplink carrier, said Internet protocol address encrypted using a second encryption key.

9. The method of claim 8 , wherein said base station receives said Internet protocol address from another network node.

10. The method of claim 7 , wherein said synchronization signal:

a) comprises a primary synchronization signal and a secondary synchronization signal on said downlink carrier;

b) indicates a physical cell ID for a cell comprising said downlink carrier;

c) provides timing information for said downlink carrier; and

d) is transmitted by said base station using a third plurality of OFDM subcarriers in the center of the frequency band of said downlink carrier on the first and sixth subframe of each frame.

11. The method of claim 7 , further comprising receiving random access parameters from said base station, said parameters employed for generating said random access preamble.

12. The method of claim 7 , wherein said automobile data is encrypted using said first encryption key and an additional parameter that changes every 1 to 100 msec.

13. The method of claim 7 , further comprising transmitting a first message to said server over said non-GBR bearer, said first message encrypted using said first encryption key; said first message triggers establishing a connection with said server.

14. The method of claim 7 , further comprising receiving a second message from said server over said non-GBR bearer, said second message triggers start of transmission of said automobile data from said wireless device to said server; said second message encrypted using said second encryption key.
